It is an object of this invention to provide a yarn guide apparatus forspinning frames, twisters and the like comprising an annular member or"ring having a groove extending around its inner surface in which a ringis loosely mounted and-towh'ich yarn may be directed from a suitningframe, the yarn passing between the outer periphery of the last-namedring and the bottom of the groove in which it is disposed and thenextending-to'a-rotating bobbin.

t is another objector-this invention to provide a ring for spinningframes and the like havingupper and lower annular members having theirinner proximate edges cut away, so that when they are placed insuperposed relation a groove substantially semi-circular in crosssection will be provided for loosely receiving a floating ring andhaving means for securing the upper and-lower members together and alsosecuring the upper and lower members to the ring rail of the spinningframe, and to further provide coinciding slots in the upper and lowermembers extending from the inner to the outer surfaces thereof and beingdisposed substantially tangent to the curvature of the inner surface ofthe upper and lower members and communicating with the groove in theinner surface of the upper and lower members to thus provide means forrapidly threading the yarn, between the periphery of the second ring andthe bottom of the groove in the inner face of the upper and lowermembers, it being understood that the ring rail should have a coincidingslot therein to facilitate passing the yarn through the slot in the ringduring the threading operation.

Since a traveler is not employed in my improved spinning and twistingring, it is seen that the use of a lubricant is eliminated and this alsoinsures that the yarn, regardless of whether it is a wet or dry twistyarn, will be free of lubricant or stains which normally collect on theyarn as it passes through the traveler on other types of spinning andtwisterrings.

Referring morespecilically to the drawings the It indicates a bolsterrail'which supports a; plurality ofb'olste'r's I I, only one of which isshown in the' drawingsi Thisbolster rotatably conventionsrefivihg means,not' shown; are connec'td for 't'rans'rriittin'g rotation tdthe spindleI3. This spindle I3 has a bobbin I4 mounted thereon on which yarn I5 isadapted to be wound.

Disposed a substantial distance above the bolster rail I8 is avertically movable ring rail I9 which is provided with a plurality ofopenings 29 only one of which is shown in the drawings. This ring railI9 is driven by conventional means, not shown, to move up and down withrespect to the bobbin M so as to lay the yarn I5 onto the bobbin evenly.

The numeral 2| broadly designates the ring as a whole which comprisesupper and lower ring members 22 and 23 respectively. The proximate inneredges of each of the ring members 22 and 23 are provided with coincidingsubstantially quarter-circular grooves which, when the ring members 22and 23 are assembled, form a groove 24 around the inner face of the ring2| in Figures 3 and 4.

The upper and lower ring members 22 and 23 are secured together by bolts26 which also secure the members 22 and 23 to the ring rail I9, the ring21, of course, being positioned in cooperating alinement with theopening 2|! in the ring rail IQ. The members 22 and 23 are provided withcoinciding slots 2'1 which extend from the outer to the inner surfacesof the ring 2| and these coinciding slots 2'! are disposed substantiallytangent to the inner surface of the ring 2|. In order to facilitate thethreading of yarn through the coinciding slots 21 in the members 22 and23 it is preferable that the ring rail I9 be provided been stated, otherobjects will appear as the de- 'scription proceeds, when taken-inconnection with the accompanying drawings, in whichwith a plurality ofslots 38, there being one slot 36 for each of the rings 2| and this slot30 coincides with the slot 21 in the members 22 and 23.

Also, before the upper and lower members 22 and 23 are assembled in themanners shown in Figures 3 and 4, a continuous floating ring 3|, ofsubstantially less thickness than the width of the groove 24 and ofsubstantially less overall diameter than the diameter of the groove 24,is mounted in the groove 24 between the members 22 and 23. It will benoted in Figures 3 and 4 that this floating ring 3| is of substantiallythe same inner diameter as the inside diameter of the members 22 and 23,however, the outside diameter of the ring 3| is substantially less thanthe diameter at the bottom of the groove 24 in the members 22 and 23 andis thus loosely confined within the grOOVe 24. It is preferable that theouter peripheral edges of the ring 3| be rounded, as at 32, and that thering 3| be polished to avoid breaking the yarn as it passes thereby.Also in Figure 4, it is preferred that the peripheral edge of'the groove24 at the upper member 22 be rounded as at 33 and that the inner surfaceof the member 22 be polished to further prevent the yarn from breakingas it passes thereby.

It is thus seen that upon placin an empty bobbin H! on the spindle l3,an operator may thread the yarn through the coinciding slots 36 and 21in the ring rail l9 and the guiding ring 2| and the yarn will then passdownwardly from a suitable source, such as the drawin rolls of aspinning frame, and will then engage the inner surface of the uppermember 22 and pass into the groove 24 and around the outer periphery ofthe ring 3! and thus to the bobbin I l. The spindle l3 being driven, theyarn I5 is then wound about the bobbin l4 and, at the same time, theyarn I5 moves around the floating ring 3|, the outer ring 2| remainingstationary.

In the drawings and specification there has been set forth a preferredembodiment of the in- Gil vention, and although specific terms are em-'ployed, they are used in a generic and descriptivesense only, and notfor purposes of limitation, thescope of the invention being defined inthe claim.-
